Notes:
A small glacial outburst flood occurred at Mount Rainier National Park on Saturday, October 27, 2012 at approximately 9:00 PM. This event, while significant, was localized in scale, caused no damage to park facilities, and was not volcanic in origin. It likely originated from the Nisqually Glacier as result of moderate to intense rainfall. A stream gage located at Longmire registered a 2.8 foot (0.85 meter) rise in river water level between 8:30 and 9:45 pm and the spike was seen on other gages downstream of the park. Field data concurs with the stream gage and shows evidence of a several-foot surge of water in the Nisqually River.

So this is interesting... There's a clear seismic signal that shows up park-wide at approx 2012-10-27 03:07:00 UTC ish...

I have an email out to Steve and Seth to figure out what this is.
